drm/v3d: Delete v3d_dev->pdev
We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too
To avoid having to pull in some big headers I implemented the casting
function as a macro instead of a static inline. Typechecking thanks to
container_of still assured.
But also a bit a bikeshed, so feel free to ignore.
v2: More parens for v3d_to_pdev macro (checkpatch)
